问题 It is based on technology that already exists-—it’s not a pie in the sky prediction. The underlined part means______.
选项 A、unrealistic
B、marvelous
C、objective
D、pessimistic
答案A
解析 习语理解题。原句中pie in the sky意为“不能保证实现的诺言；渺茫的希望”，而unrealistic意为“不切实际的；不现实的”，符合句意，故[A]为答案。marvelous意为“了不起的；非凡的；令人惊异的”；objective意为“客观的；目标的”；pessimistic意为“悲观的，厌世的；悲观主义的”。
